ggdonutchart | R Documentation |
Create a donut chart.
ggdonutchart( data, x, label = x, lab.pos = c("out", "in"), lab.adjust = 0, lab.font = c(4, "plain", "black"), font.family = "", color = "black", fill = "white", palette = NULL, size = NULL, ggtheme = theme_pubr(), ... )
data |
a data frame |
x |
variable containing values for drawing. |
label |
variable specifying the label of each slice. |
lab.pos |
character specifying the position for labels. Allowed values are "out" (for outside) or "in" (for inside). |
lab.adjust |
numeric value, used to adjust label position when lab.pos = "in". Increase or decrease this value to see the effect. |
lab.font |
a vector of length 3 indicating respectively the size (e.g.: 14), the style (e.g.: "plain", "bold", "italic", "bold.italic") and the color (e.g.: "red") of label font. For example lab.font= c(4, "bold", "red"). |
font.family |
character vector specifying font family. |
color, fill |
outline and fill colors. |
palette |
the color palette to be used for coloring or filling by groups. Allowed values include "grey" for grey color palettes; brewer palettes e.g. "RdBu", "Blues", ...; or custom color palette e.g. c("blue", "red"); and scientific journal palettes from ggsci R package, e.g.: "npg", "aaas", "lancet", "jco", "ucscgb", "uchicago", "simpsons" and "rickandmorty". |
size |
Numeric value (e.g.: size = 1). change the size of points and outlines. |
ggtheme |
function, ggplot2 theme name. Default value is theme_pubr(). Allowed values include ggplot2 official themes: theme_gray(), theme_bw(), theme_minimal(), theme_classic(), theme_void(), .... |
... |
other arguments to be passed to be passed to ggpar(). |
The plot can be easily customized using the function ggpar(). Read ?ggpar for changing:
main title and axis labels: main, xlab, ylab
axis limits: xlim, ylim (e.g.: ylim = c(0, 30))
axis scales: xscale, yscale (e.g.: yscale = "log2")
color palettes: palette = "Dark2" or palette = c("gray", "blue", "red")
legend title, labels and position: legend = "right"
plot orientation : orientation = c("vertical", "horizontal", "reverse")
